I am starting to pick up a few GIS courses and cartography courses at university. I was wondering if anyone out there uses GIS software for the Mac.

My wife is a GIS guru AND a Mac user, but she has to use a PC for ESRI ArcInfo/ArcView. You could of course use Parallels to run PC apps within OSX or just install Windows on an Intel Mac to run GIS apps. She does everything else [e.g. Photoshop or InDesign work] within OSX.

I have a project that will require some GIS mapping... anyone want to offer (informed) suggestions for Native OS X GIS software? I'm downloading QuantumGIS (and the GRASS, GDAL and GSL frameworks) to test it out, but happy to go another direction if there's a better option out there. Looked at a couple of others that rely on X11, but I'd like something that has a nice OS X UI, not a butt-ugly Windows or Linux interface.
